Damped DNLW
From DispersiveWiki
The damped DNLW
in three dimensions is known to be locally well-posed in any sub-critical regularity s > 1, and has scattering in H3 Smh-p. It would be interesting to see whether one has local well-posedness in the critical energy regularity H1. It is an example of a linear-derivative nonlinear wave equation.
